Be sure switch is off before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents. n Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury. n Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations. n Use safety equipment. Always wear eye protection. Dust mask, nonskid safety shoes, hard hat, or hearing protection must be used for appropriate conditions. n Do not wear loose clothing or jewelry. Contain long hair. Loose clothes, jewelry, or long hair can be drawn into air vents. n Do not use on a ladder or unstable support. Stable footing on a solid surface enables better control of the tool in unexpected situations. WARNING: Read and understand all instructions. Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury. SAVE THESE INSTRUCTIONS WORK AREA � Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents. n Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes. n Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control. ELECTRICAL SAFETY TOOL USE AND CARE n Double insulated tools are equipped with a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double insulation eliminates the need for the threewire grounded power cord and grounded power supply system. n Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is grounded. n Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. n Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges, or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock. n When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric shock. n Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control. n Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed. n Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired. n Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally. n Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users. n Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges are less likely to bind and are easier to control. n Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tools operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools. n Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool. n Keep the tool and its handle dry, clean and free from oil and grease. Always use a clean cloth when cleaning. Never use brake fluids, gasoline, petroleum-based products, or any strong solvents to clean your tool. Following this rule will reduce the risk of loss of control and deterioration of the enclosure plastic. PERSONAL SAFETY n Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury. n Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. 3 GENERAL SAFETY RULES SERVICE n When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock or injury. n Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury. SPECIFIC SAFETY RULES n DANGER! Keep hands away from cutting area and blade. Keep your second hand on the auxiliary handle or motor housing. If both hands are holding the saw, they cannot be cut by the blade. n Keep your body positioned to either side of the saw blade, but not in line with the saw blade. KICKBACK could cause the saw to jump backwards. (See “Causes And Operator Prevention Of Kickback” later.) n Do not reach underneath the work. The guard cannot protect you from the blade below the work. n Check lower guard for proper closing before each use. Do not operate saw if lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If saw is accidentally dropped, lower guard may be bent. Raise the lower guard with the retracting handle. Make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut. n Check the operation and condition of the lower guard spring. If the guard and the spring are not operating properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged parts, gummy deposits, or a buildup of debris. n Lower guard should be retracted manually only for special cuts, such as "Pocket Cuts" and "Compound Cuts." Raise lower guard by retracting handle. As soon as blade enters the material, lower guard must be released. For all other sawing, the lower guard should operate automatically. n Always observe that the lower guard is covering the blade before placing saw down on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released. n NEVER hold piece being cut in your hands or across your leg. It is important to support the work properly to minimize body exposure, blade binding, or loss of control. n Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator. n When ripping, always use a rip fence or straight edge guide. This improves the accuracy of the cut and reduces the chance for blade binding. n Always use blades with correct size and shape (diamond vs. round) arbor holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control. n Never use damaged or incorrect blade washers or bolts. The blade washers and bolts were specially designed for the saw for optimum performance and safety of operation. CAUSES AND OPERATOR PREVENTION OF KICKBACK: Kickback is a sudden reaction to a pinched, bound, or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece toward the operator. When the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator. If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator. Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions, as given below: n Maintain a firm grip with both hands on the saw and position your body and arm to allow you to resist KICKBACK forces. KICKBACK forces can be controlled by the operator, if proper precautions are taken. n When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion, or KICKBACK may occur. Investigate and take corrective actions to eliminate the cause of blade binding. n When restarting a saw in the workpiece, center the saw blade in the kerf and check that saw teeth are not engaged into the material. If saw blade is binding, it may walk up or KICKBACK from the workpiece as the saw is restarted. n Support large panels to minimize the risk of blade pinching and KICKBACK. Large panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel. 4 SPECIFIC SAFETY RULES n Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. A wire gage size (A.W.G.) of at least 12 is recommended for an extension cord 50 feet or less in length. A cord exceeding 100 feet is not recommended. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. n Inspect for and remove all nails from lumber before using this tool. Following this rule will reduce the risk of serious personal injury. n Do not use dull or damaged blade. Unsharpened or improperly set blades produce narrow kerf which causes excessive friction, blade binding and KICKBACK. n Blade depth and bevel adjusting locking levers must be tight and secure before making cut. If blade adjustment shifts while cutting, it may cause binding and KICKBACK. n Use extra caution when making a “Pocket Cut” into existing walls or other blind areas. The protruding blade may cut objects that can cause KICKBACK. n Know your power tool. Read operator’s manual carefully. Learn its applications and limitations, as well as the specific potential hazards related to this tool. Following this rule will reduce the risk of electric shock, fire, or serious injury. n Always wear safety glasses. Everyday eyeglasses have only impact-resistant lenses; they are NOT safety glasses. Following this rule will reduce the risk of serious personal injury. n Protect your lungs. Wear a face or dust mask if the operation is dusty. Following this rule will reduce the risk of serious personal injury. n Protect your hearing. Wear hearing protection during extended periods of operation. Following this rule will reduce the risk of serious personal injury. n Inspect tool cords periodically and, if damaged, have repaired at your nearest authorized service center. Constantly stay aware of cord location. Following this rule will reduce the risk of electric shock or fire. n Check damaged parts. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center. Following this rule will reduce the risk of shock, fire, or serious injury. LASER GUIDE WARNINGS: The laser guide radiation used in the Ryobi circular saw is Class IIIa with maximum <5mW and 650nm wavelengths. These lasers do not normally present an optical hazard although staring at the beam may cause flash blindness. n Avoid direct eye exposure when using the laser guide. n The laser shall be used and maintained in accordance with the manufacturer’s instructions. n Never aim the beam at a person or object other than the workpiece. n Always ensure the laser beam is aimed at a sturdy workpiece without reflective surfaces. Shiny reflective sheet metal or similar shiny materials are not suitable for laser use. n All repairs should be made by an authorized service representative or the laser manufacturer. n Save these instructions. Refer to them frequently and use them to instruct others who may use this tool. If you loan someone this tool, loan them these instructions also. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: • lead from lead-based paints, • crystalline silica from bricks and cement and other masonry products, and • arsenic and chromium from chemically-treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. 5 SYMBOLS Some of the following symbols may be used on this tool.

SAVE THESE INSTRUCTIONS 7 ELECTRICAL DOUBLE INSULATION EXTENSION CORDS Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual threewire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded. When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to handle the current the tool will draw. An undersized cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to determine the minimum wire size required in an extension cord. Only round jacketed cords listed by Underwriter’s Laboratories (UL) should be used. When working outdoors with a tool, use an extension cord that is designed for outside use. This type of cord is designated with “WA” on the cord’s jacket. Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation. WARNING: The double insulated system is intended to protect the user from shock resulting from a break in the tool’s internal insulation. Observe all normal safety precautions to avoid electrical shock. NOTE: Servicing of a tool with double insulation requires extreme care and knowledge of the system and should be performed only by a qualified service technician. For service, we suggest you return the tool to your nearest authorized service center for repair. Always use original factory replacement parts when servicing. **Ampere rating (on tool data plate) 0-2.0 2.1-3.4 Cord Length ELECTRICAL CONNECTION This tool has a precision-built electric motor.

Failure to do so could result in objects being thrown into your eyes resulting in possible serious injury. No more than 1/4 inch KICKBACK - BLADE SET TOO DEEP WARNING: Fig. 7 Do not use any attachments or accessories not recommended by the manufacturer of this tool. The use of attachments or accessories not recommended can result in serious personal injury. INCORRECT SUPPORT APPLICATIONS You may use this tool for the purposes listed below: n Cross cutting/rip cutting n Bevel cutting n Pocket cutting KICKBACK See Figures 7 - 9. Kickback occurs when the blade stalls rapidly and the saw is driven back towards you. Blade stalling is caused by any action which pinches the blade in the wood. Fig. 8 CORRECT SUPPORT DANGER: Release switch immediately if blade binds or saw stalls. Kickback could cause you to lose control of the saw. Loss of control can lead to serious injury. To guard against kickback, avoid dangerous practices such as the following: n Setting blade depth incorrectly n Sawing into knots or nails in workpiece n Twisting the blade while making a cut n Making a cut with a dull, gummed up, or improperly set blade n Supporting the workpiece incorrectly n Forcing a cut n Cutting warped or wet lumber n Operating the tool incorrectly or misusing the tool Fig. 9 13 OPERATION To lessen the chance of kickback: n Keep the blade at the correct depth setting. The depth setting should not exceed 1/4 in. (6.35 mm) below the material being cut. n Inspect the workpiece for knots or nails before cutting. Never saw into a knot or nail. n Make straight cuts. Always use a straight edge guide when rip cutting. This helps prevent twisting the blade. n Use clean, sharp, and properly set blades. Never make cuts with dull blades. n Support the workpiece properly before beginning a cut. n Use steady, even pressure when making a cut. Never force a cut. n Do not cut warped or wet lumber. n Hold the saw firmly with both hands and keep your body in a balanced position so as to resist the forces if kickback should occur. No more than 1/4 inch LOWER BLADE GUARD IS IN UP POSITION WHEN MAKING A CUT WARNING: Fig. 10 DANGER: When using the saw, always stay alert and exercise control. Do not remove the saw from the workpiece while the blade is moving. When sawing through work, lower blade guard does not cover blade on the underside of work. Since blade is exposed on underside of work, keep hands and fingers away from cutting area. Any part of your body coming in contact with moving blade will result in serious injury. SAW BLADES The best of saw blades will not cut efficiently if they are not kept clean, sharp, and properly set. Using a dull blade will place a heavy load on the saw and increase the danger of kickback. Keep extra blades on hand, so that sharp blades are always available. Gum and wood pitch hardened on blades will slow the saw down. Remove saw blade from the saw and use gum and pitch remover, hot water, or kerosene to remove these accumulations. DO NOT USE GASOLINE. CAUTION: Never use saw when guard is not operating correctly. Check the guard for correct operation before each use. The guard is operating correctly when it moves freely and readily returns to the closed position. If you drop the saw, check the lower blade guard and bumper for damage at all depth settings before reuse. BLADE GUARD SYSTEM See Figure 10. The lower blade guard attached to the circular saw is there for your protection and safety. Do not alter it for any reason. If it becomes damaged, do not operate the saw until you have the guard repaired or replaced. Always leave guard in operating position when using the saw. 14 OPERATION STARTING/STOPPING THE SAW See Figure 11. To start the saw: Depress the switch trigger. Always let the blade reach full speed, then guide the saw into the workpiece. SWITCH WARNING: The blade coming in contact with the workpiece before it reaches full speed could cause the saw to “kickback” towards you resulting in serious injury. To stop the saw: Release the switch trigger. After you release the switch trigger, allow the blade to come to a complete stop. DO NOT remove the saw from the workpiece while the blade is moving. Fig. 11 WARNING: DEPTH OF CUT SCALE Failure to unplug the tool could result in accidental starting causing serious injury. ADJUSTING BLADE DEPTH See Figure 12. Always keep correct blade depth setting. The correct blade depth setting for all cuts should not exceed 1/4 in. below the material being cut. More blade depth will increase the chance of kickback and cause the cut to be rough. For more depth of cut accuracy, a scale is located on the upper blade guard. To adjust the blade depth: n Unplug the saw. n Loosen depth adjustment knob. n Determine the desired depth of cut. n Locate depth of cut scale on back of upper blade guard. n Hold base flat against the workpiece and raise or lower saw until the indicator mark on bracket aligns with notch on blade guard. n Tighten depth adjustment knob securely. BASE 15 DEPTH ADJUSTMENT KNOB Fig. 12 OPERATION OPERATING THE SAW See Figures 13 - 15. It is important to understand the correct method for operating the saw. Refer to the figures in this section to learn the correct and incorrect ways for handling the saw. WARNING: To make sawing easier and safer, always maintain proper control of the saw. Loss of control could cause an accident resulting in possible serious injury. DANGER: When lifting the saw from the workpiece, the blade is exposed on the underside of the saw until the lower blade guard closes. Make sure the lower blade guard is closed before setting the saw down. Fig. 13 To make the best possible cut: n Hold the saw firmly with both hands. n Avoid placing your hand on the workpiece while making a cut. n Support the workpiece so that the cut is always on your right. n Support the workpiece near the cut. n Clamp the workpiece securely so that the workpiece will not move during the cut. n Avoid placing the saw on the part of the workpiece that will fall off when the cut is made. n Place the workpiece with the “good” side down. n Draw a guideline along the desired line of cut before beginning your cut. n Keep the cord away from the cutting area. Always place the cord to prevent it from hanging up on the workpiece while making a cut. Fig. 14 DANGER: If the cord hangs up on the workpiece during a cut, release the switch trigger immediately. Unplug the saw and reposition the cord to prevent it from hanging up again. DANGER: Using a saw with a damaged cord could result in serious injury or death.

LASER GUIDE BUTTON WARNING: Do not stare into the laser beams or turn the lasers on when the tool is not in use. Failure to heed this warning could result in possible serious personal injury. The laser guides will generate a red colored laser beam on the work surface in front of and behind the saw when turned on. The front laser aids in following the line of cut when cutting the workpiece. The rear laser aids in aligning plunge cuts and following the kerf when exiting the workpiece. Fig. 16 NOTE: The laser units come from the factory already installed and aligned. If the lasers become misaligned after time, refer to the Adjustments section later in this manual. n Mark the line to be cut on the workpiece. n Adjust the depth and angle of the cut as needed. n Plug the tool into a power supply and press the laser guide button to activate the laser. n Start the motor. NOTE: Do not touch the blade to the workpiece until the saw has reached maximum speed. n Slowly push the saw forward into the workpiece. NOTE: Keep the laser beam on the marked line on the workpiece for precision cutting. n Once the cut is complete, allow the saw to come to a complete stop before turning off the laser. n Unplug the saw. LENGTH OF CUT SCALE LENGTH OF CUT SCALE See Figure 17. The saw is equipped with a length of cut scale on its base. It is parallel with the saw blade and you can use it to measure the distance into the material the blade cuts. NOTE: Six inches is the maximum length of cut that you can measure. Also, it is accurate only when the depth of cut is set at full maximum depth. 17 Fig. 17 OPERATION CROSS CUTTING/RIP CUTTING TOP VIEW OF SAW See Figures 18 - 20. When making a cross cut or rip cut, align the line of cut with the outer blade guide notch on the base as shown in the figure. Since blade thicknesses vary, always make a trial cut in scrap material along a guideline to determine how much, if any, you must offset the guideline to produce an accurate cut. BLADE GUIDE NOTCH NOTE: The distance from the line of cut to the guideline is the amount you should offset the guide. TO RIP CUT WITHOUT EDGE GUIDE See Figure 19. Use a guide when making long or wide rip cuts with the saw. n Secure the workpiece. Fig. 18 GUIDELINE n Clamp a straight edge to the workpiece using C-clamps. n Saw along the straight edge to achieve a straight rip cut. NOTE: Do not bind the blade in the cut. STRAIGHT EDGE TO RIP CUT WITH EDGE GUIDE See Figure 20. n Secure the workpiece. n Position the face of the edge guide firmly against the edge of workpiece. n Guide the saw along the edge to achieve a straight rip cut. NOTE: The guiding edge of the workpiece must be straight for your cut to be straight. Use caution to prevent the blade from binding in the cut. GUIDELINE C-CLAMPS WORKPIECE Fig. 19 WORKPIECE GUIDELINE EDGE GUIDE 18 Fig. 20 OPERATION BEVEL CUTTING MOTOR HOUSING See Figures 21 - 22. To make the best possible cut: n Align the line of cut with the inner blade guide notch on the base when making 45° bevel cuts. n Make a trial cut in scrap material along a guideline to determine how much you should offset the guideline on the cutting material. n Adjust the angle of the cut to any desired setting between zero and 51.5°. BEVEL SCALE TO ADJUST BEVEL SETTING See Figure 21. n Unplug the circular saw. n Loosen bevel adjustment knob. n Raise motor housing end of saw until you reach desired angle setting on bevel scale. n Tighten bevel adjustment knob securely.
